Please answer and explain the following two part question. Thanks.

A hard disk has four surfaces (that\'s top and bottom of two platters). Each track has 2, 048 sectors and there are 131, 072 (2^17) tracks per surface. A block holds 512 bytes. The disk is not \"zoned.\" What is the total capacity of this disk? Show your work. Given the disk in Part 1, how much data can be accessed without moving the disk heads. (That, is, what is the capacity of one cylinder?)

Solution

part1) Each platter has four surface . no of surface 17/4 =4.25 approx 4 platter

2) Number of sectors per track = no of sectors per cylinder 2048/17 =120.4705

3) number of surfaces*sector per track*number of sectors * 512= Total storage = 4*120*2048*512 = 503316480

so the storage capacity is 5GB

part2)Cyliner capacity = Number of surfaces*track capacity = 4*Number of sectors per track*bytes per sector =4*2048/17*512 =4*120*512=245760 bytes = 0.24MB
